Katrina learns dirt biking for Zoya Akhtar's next

The actress is said to be impressed with the script and is throwing herself into all sorts of stunt training to prepare for her role.

"Though Katrina is in London visiting her family, she is making time to meet deep sea diving instructors. She is very kicked about the stunts in the film - be it dirt bike riding for which she has already started training or deep sea diving for which she is soon to enroll in classes on her return from London," a source close to Katrina said in a press statement.

"Katrina has never attempted anything like this before but has already started preparing for her role," added the source. The cast of "Running with the Bulls" also includes Hrithik Roshan, Farhan Akhtar and Abhay Deol.
